Designed primarily for use with crushers where water sprays are not effective or hard to wet substances. Spray Treatment Points • Hoppers –Hoppers require a brief but high volume burst of spray when trucks, loaders, or railcars dump. • Crushers –Spray treatment at crushers is critical. Spray treatment controls emissions and relies oncomparable among coal types, and the size distribution of the dust was uniformly reduced by the water spray. Since water spray capture efficiency remained essen- tially uniform, the dust concentration at the end of the spray period was a function of the amount of dust generated. Therefore, a particular water spray …
